classification, testing items and testing standards of chemical additives

March 28, 2019

chemical additives, especially chemical additives required by a certain industry, have a wide variety, including but not limited to metal processing additives, plastic additives, paper additives, building additives, water treatment additives, coating additives, leather additives, textile printing and dyeing additives, etc

I: product segmentation of chemical additives

1 Testing of rubber and plastic additives

plasticizers, flame retardants for plastics, antioxidants, stabilizers, foaming agents, rubber additives, accelerators, antioxidants, defoamers, reclaimed rubber activators, plasticizers, etc

2. Water treatment agent detection

corrosion inhibitor, water quality stabilizer, flocculant, bactericide and algicide, chelating agent, etc

3. Surfactant detection

stearic acid, sodium dodecylbenzene sulfonate, quaternary ammonium compounds, industrial ethoxylated fatty amines, industrial sodium tripolyphosphate, sodium ethoxylated alkyl sulfate, layered crystalline sodium disilicate, industrial alkane sulfonates, fatty acid glycerides, etc

4. Paint additives detection

light stabilizer, leveling agent, anti scaling agent, drying agent, pigment dispersant, etc

5. Testing of building additives

mortar additives, cement concrete admixtures, stone additives, cement grinding aids, etc

6. Catalyst detection

but new investment projects are still on the pipeline, such as Malaysian chemical catalyst, shift catalyst, methanation catalyst, ammonia synthesis catalyst, vanadium catalyst for sulfuric acid production, hydrodesulfurization catalyst, gas purification catalyst, etc

II: test items of chemical additives

physical indicators: pH value, chromaticity, crystallization point, density, whiteness, particle size, oil absorption, activity measurement, pH, boiling range, etc

chemical indicators: purity and impurity content, evaporation residue, acidity, hydroxyl compounds, polymerization inhibitors, total aldehyde content, compound content, peroxide, undoubtedly provide energy for the industrial transformation of Nanzhuang. The content of simple substances, moisture, chloride, alcohol content, heavy metal content, burning residue, insoluble content, water-soluble content, sieve residue content, bulk density, looseness, volatile matter at 105 ℃ and other Chinese coatings
